Synopsis ========
pam_ldap contains a vulnerability that may allow a remote user with a locked account to gain unauthorized system access.
Background ==========
pam_ldap is a Pluggable Authentication Module which allows authentication against LDAP directories.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-auth/pam_ldap < 183 >= 183
Description ===========
Steve Rigler discovered that pam_ldap does not correctly handle "PasswordPolicyResponse" control responses from an LDAP directory. This causes the pam_authenticate() function to always succeed, even if the previous authentication failed.
Impact ======
A locked user may exploit this vulnerability to bypass the LDAP authentication mechanism, possibly gaining unauthorized access to the system.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All pam_ldap users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-auth/pam_ldap-183"
References ==========
